Review the following Considerations before you use the immutable snapshot feature for INFINIDAT Array.
-
The clients and Access nodes must be on Platform Release 2024E (11.36) or later.
-
You can only set days-based retention on the snapshot copies. Extended retention is not supported.
-
The maximum allowed retention for INFINIDAT storage array is 365 days.
-
The snapshot immutability is not inherited by clones or mounts. Only the original snapshot is immutable.
-
If the snapshot primary copy is marked as immutable and a vault/replica copy exists, both copies will be marked as immutable. The retention periods for these copies can be different and independent of each other. However, it is also possible to make only the vault/replica copy immutable.
-
If the retention settings for the immutable snap copies are modified, existing snapshots will still adhere to their original retention, and only new snapshots will follow the new retention settings.
